TkCVS is a cross-platform, Tcl/Tk-based GUI for the CVS and Subversion configuration management systems. It displays the status of the files in the current working directory, and provides buttons and menus to execute CVS, Subversion, or RCS commands on the selected files. The Log Browser displays a branch diagram of the revision history. The Module Browser extends CVS with facilities for a user-friendly listing of modules in the repository. TkDiff is included for browsing and merging your changes.

The PLCIO library reads and writes data to a variety of programmable logic controllers
(PLC). Now in its 20th year, PLCIO is a stable platform allowing the programmer to address
PLC memory by their tag names for different data types, regardless of the computer
architecture, with the PLC linked either directly or remotely. PLCIO abstracts the
application and communications layers so that the programmer of the business and database
logic need not worry about the communication details. Full source code is included, as are
samples and a CGI interface for PLC access from a Web browser. It runs under Linux, HP-UX,
Solaris, and QNX, and can be used as a replacement for the aging Interchange software by
Allen-Bradley. PLCIO supports the Serial DF1 and Ethernet protocols of the Allen-Bradley
PLC-5, SLC 500, ControlLogix, CompactLogix, and MicroLogix PLCs (using the CIP protocol),
the Modicon Quantum PLC, the Wago 750-842 PLC, the Siemens Step5 PLC (using the AS511 serial
protocol or via Ethernet using the INAT Echolink), and the Siemens Step 7 200, 300, and
400-series CPUs. It also supports communicating directly with an I/O bus terminal such as
the Beckhoff BK9105 or the Phoenix Contact FL IL 24 BK ETH/IP-PAC.

Rover provides a means of executing commands on remote machines via SSH, Telnet, or Rlogin. Connections are made and then managed using the Expect for Perl module. Rover can process many hosts in parallel. It comes with two interface programs, rover and rovergtk. The first is a command line tool with a built-in shell and batching capabilities; the other uses a Gtk interface to configure and use Rover.

Kobldes makes it possible for the designer to model building information and uses POV-Ray for visualization. It is also programmed using the POV-Ray screen description language (SDL). The goal of is to create a fully functioning building information modeling and management tool for designing buildings. It currently allows the designer to accomplish basic tasks with building components such as building levels and spaces in the process of solving design problems. In the near future, it will compute and make available information about the building such as sizes/volumes (such as an area for painting in a particular room), requirement checks (e.g. spatial conformance), and Property checks (e.g. calculating the solar savings factor).

Protocol Buffers Editor is a viewer and editor for Google's Protocol Buffers binary files. Information is displayed as a tree and can be updated, saved as XML or HTML, and compared to another saved file.
